线轴

1.High processing accuracy due to superprecision linear motion pair adopted in moving parts.

运动部分采用高精度承运动副,组角精度高。

2.It required three spools, each containing approximately 900 feet of number 27 Heavy Formvar wire for the primary sections.

这个工作需三个，每个上面有900英尺27号制初级组。

3.The three wires were fed from the three spools and wound as one wire; thus comprising the trifilar terminology.

三条从三个出成一条，从而符合三并求。
